Abstract

Underwater image de-noising and enhancement is necessary because of underwater image with low signal to noise ratio, low contrast, and poor image quality, due to that pre-processing is necessary before applying wavelet de-noising. Proposed algorithms used Adaptive wavelet combining adaptive threshold selection with adaptive output of the threshold function for image de-noising and CLAHE for enhancement of de-noised image. Finally the output shows that the proposed method removes noise effectively, also improves Peak Signal to Noise Ratio and better visual appearance, wavelet de-noising with enhancement gives desirable results in terms of Peak Signal to Noise Ratio Due to the advantages of its low entropy, multi-resolution characteristics, removing the correlation and choosing base flexibility, wavelet de-noising method more and more attracts people's attention.
